Although I already 'pip install soundfile' ,I got the error :

      1 filename = "./data/SpeechCommands/speech_commands_v0.02/yes/00f0204f_nohash_0.wav"
----> 2 waveform, sample_rate = torchaudio.load(filepath=filename, num_frames=3)
      3 print(f'waveform tensor:{waveform}')
      4 waveform, sample_rate = torchaudio.load(filepath=filename, num_frames=3, offset =2)
      5 print(waveform)

RuntimeError: No audio I/O backend is available

Answer 1

I think, the problem is with python versions.

Try one of them, please.

• pip install PySoundFile
• pip install SoundFile
